According to my experience this is the best software in terms of User Interface among all others which were designed by the companies in its class. The good thing about this software is that simple,robust and its FREE OF CHARGE . The ability to compare cross platforms is the paramount feature of this software.

Method development is spot on. When it comes to data analysis and quantification there is still some space to improve by looking from the company designed softwares.

I am more than happy using this software at my work.
